7. Instant heating function
In situations when all the water is used up in the heater, the instant heating function allows users to get
40ºC of water in 2 minutes instead of waiting for 30 minutes. Press the 'Instant' button to enter instant
heating mode.
The instant heating function will override any existing heating functions while it is activated. Water is
heated very quickly in this mode. When the desired temperature is reached, the heating light will go
off and the water heater will resume normal operation. The water heated is sufficient for a single
shower.
